The first state-licensed marijuana stores are still almost a year away, but business-minded people are already chasing profits. Today, entrepreneurs are pitching their pot-related ideas to dozens of wealthy investors in Seattle.

San Francisco-based ArcView Investor Network arranged the private forum akin to the TV show “Shark Tank.” Entrepreneurs will have a few minutes to pitch their idea—which includes everything from better grow lights to handheld vaporizers, to mobile apps for marijuana retailers—and explain why their idea is a worthy investment.
